Side A refines a core ranking algorithm with clear, well-justified tie-breaking logic and backs the change with multiple targeted unit tests verifying the new behavior (attach-before-isolate, zip ordering). Side B adds a useful pool-voting feature across several files but introduces no new tests for the added endpoint/behavior and has more surface area for subtle bugs (e.g., untested pool validation, dedupe assumptions), making it riskier and less rigorously verified than A's focused algorithmic fix.

council reasoning
A upgrades the core pair-selection algorithm (bridge sub-priorities for spanning-tree growth, then zip-order adjacent rank refinement with established-component tracking) and locks it in with targeted tests—ongoing quality of every suggested vote. B adds real product surface (pool query param, children button, threading pool through vote UI/JS), but it is largely parameter plumbing over the existing suggest_next_pair_in_pool path rather than deeper ranking design.
Side A makes a substantive change to the core pair-selection algorithm by introducing component-aware bridge priorities, rank-based refinement ('zip' ordering) once a pool is connected, and adds targeted tests covering the new behavior. Side B mainly wires an existing capability into the UI and routing by adding pool-scoped `/vote` navigation and context propagation; while useful, it is largely integration work built on the underlying pair-selection logic rather than improving that logic itself.

message
[5db58b98] Improve vote pair selection for spanning trees and rank refinement. Prefer attaching unranked items to established components before comparing isolates, then zip down adjacent rank-centrality pairs once the pool is fully connected, skipping pairs that already have votes.

[5350388a] Add pool-scoped voting: /vote?pool=<parent> picks pairs from children. - /vote now accepts an optional `pool` param (parent item path). When provided without left/right, it picks the first unvoted pair from the pool's children. When provided alongside left/right, it constrains "next pair" navigation to siblings within the pool. - "vote on children" button appears on item pages with ≥2 children, linking to /vote?pool=<item>. - Pool is threaded through VoteComparePost → success JS so in-page morph after voting keeps the pool context for next-pair navigation.
